, To all 'whom t may concern.'

i Be it known that we, (l) STEPHEN PAL- HEEGYI and (2) HERMAN EICHNER,(l) a subject of the King of Hungary, and (2) a citizen of the UnitedStates, residingat Detroit, in the county of .Wayne and Stateiof`Michigan, have invented certain newV and useful Improvements inWell-Pumps, of

v which the following is a specication. e

A further object of the invention `is to i provide a well pump iny whichthe weight andy gravity of the piston contained therein are utilized toelevate a vsmall column ofV water, with manually operated means forelevating the piston when the same hasI reached the lower limit of itsmovement, as

movement of the piston at any time.

With these general objects in view and 'Y others that will appear as thenature ofthe invention is. better understood, the sameV consists'in thenovel construction, 'combination and arrangementV of parts hereinaftermore'jfully described, illustrated inthe ac-l companying drawings, andthen claimed.

In the drawin s forming a part Vof this application and 1n which likevdesignating characters refer to AVcorresponding parts throughout vtheseveral views 4 VFigure 1 is a' vertical sectional view of a well pump'constructed in accordance with the present invention, showingjthe pumpcylinder and piston at the lower end of the well, as well asthe rack andpinion mecha# nism at the upper end of the well'for con-u,

Referring` more in detail to the accompanying drawing and particularlyto Fig. 1, the reference numeral 10 designates a well sunk into theground Vof any desired depth and lateral dimensions and havingpositioned therein a cylindrical filtering porous lining 11 as clearlyshown Yin Figs.

l and 2, the lower portion of the lining 11 vhaving desiredportions'as12, varied in construction to receive a change of filtering material asgravel' or charcoal as may be desired. Asis indicated, the liningll maybe formed of cylindrical sections havingcooperating adjacent engagingfaces so as to prevent the entrance of water into the well vwithout rstbeing filtered. -4

The pump mechanism arrange the well includes a cylinder 13 having aclosedbottom lll'resting upon supports 15 as indicated in Fig.` 1 whilethe lower end 14 of.4 the cylinder 13 is provided with a plurality yo fupwardly opening flap valvesf16 y V.operating 1n a mannerpresently toappear.

Well as f embodying meansV for arresting?v I5` The .cylinder 13j atgitsupper end is held spaced from the side wallsof the liningrll by brackets17 more clearly shown in Fig. 2K.

The piston associated with the cylinder d sitting,

soY

13 includes a head'lS carried by the piston rod 19 and held rigidlythereto by the inclined braces 20, the piston 18 being limited cylinder13 and projecting inwardly thereof as is shown in Fig. 1.

*in* its upward .movement by the circular band 21 fixed to'theinnerupper edge of theV A rack bar 22 is fixed to the upper end of Y theVpiston rod 19- and projects upwardly [through a central opening 23provided inthe well cover 24,' the rack bar 22 being inclosed by thehousing` 25 supported on the well cover 24 and as shown inl, extends'upfwardly into the housing tower 26 f whereby access may be had to theupper end thereof the hinged cover 27 upon the said tower, ,Y Fig. 2 isalhorizontal sectional view onV linen-Hof Fig. 1.

the same beingalso viewablethrough the [side opening 28,. "A pair ofguides: 29 is fixed lto the real-wall of the housing 25Yand engagesopposite'siides lofthe rack haras 1s shownin Fig'. 3 to holdthesameproperly f f positioned at all times whilerollerbearings L30arefjurnaled in the side wallS vOf the Y Y housing and engage the rearface .f of the` j 31supported upon the'yvell cover 24;y Iwithin Iyembodying arotatable shaft -g ournaled Y the housing 25 and havingjournaled in said standards apair of--shafts 32 .and 33 upon which arejournaled meshing pinions 34 and 35, the pinion 35 meshing with the rackbar 22. A-crank handle 36 is fixed to the shaft 32 and when rotated,similar motion ism-:oin-` municated between the meshing gears 34 and3`5,and in turn, the rack bar and piston carried thereby are reciprocated invertical directions l.as 'is plainly evident. In order to hold thepiston and rack bar in any desired position, a bracket .36 is carried bythe front wall of the housing 25 and has slidably mounted therein, a rod37 tensioned for forward sliding ino-vement as at 38 and provided with atoothed head 39 for engagement with the gear wheel 34, the same beingreleased therefrom against the tension of the -spling38 by pullingoutwardly upon the operating handle 40.

When it 'is desired to elevate water from the well 10. with 4the piston18 at substantially the limit of its lower movement, the said piston iselevated by the above described mechanism and upon such movement, the

water'lftered through the lining 11 will be drawn into the cylinder 13by Way of the upwardly opening flap valves-16, and when the piston stopssuch upward movement, the'water contained within the cylinder 13 .by itsweight willclose the iap valves 16v @and such water will be retainedwithin the cylinder. By releasing the toothed head 39 from the pinion34, the descending movement of the piston 18 increased by the desiredweight will force the 'water .out of the cylinder 13 at the lower endthereof by way ofthe stand pipe 41 supported by brackets 42 to the upperend thereof, at which point ,a discharge nozzle 43 receives the waterfrom the stand pipe 41 and delivers the same in the usual manner of apump. It will be understood that the pumping ofthe water may beinstantly stopped by permitting the toothed head K39 of thev tensionedslidingbar 37 to engage the pinion 34 and subsequentlyV arresting. thelowering movementof the rack bar 22 and theV piston 18 carried thereby.

Figs-4 and 5 show diagrammatic views of the present system embodied in ahouse wherein a flexible connection -aextends from the rod handle 4Qover a pulley -bto continue to different points or terminals as at -0-.Each floor clof the structure -e4 is provided with a water supply lVVhenlitY is desired to draw water from the supplyv -f-, the terminalslcand slidablymeunted upon the shaft JL- iXelL in the structure -e- Vandhaving connected theretothe flexible member ctrotation ofthe shaft.-1,6/ will wind` the iiexible Amemlcrer -a-f. thereon andy accordinglyp disengage the ,toothed head Safrom the rack bar and permit the waterto flow upwardly by way of the supply line to the members --f The supplymay be continuous by holding the toothed head removed from the pinion 34and subsequently holding the .cylinder -gstationary with the flexibleconnection -awound thereon by a pin and slot connection -jbetween thecylinder -gand shaft -L-. It will therefore be seen that with thepresent construction, a house of several floors, or akcountry home,without kthe use .of a city water supply, may be installed with thisapparatus and .be found to operate in .an efficient manner.

While the form` of the invention herein shown and 4described is what isbelieved to be the preferred embodiment thereof, itis nevertheless to beunderstood that Yvarious,

forms, modifications and arrangements ofV the parts may be made Withoutdeparting from the spirit and scope of the invention as claimed.
